Okay, let’s calculate this. Rustom has a broad skill set, including research, data analysis, leadership, and marketing. These skills are in demand across various industries. However, the rate will depend on the specific role and industry. Considering Rustom's skills and experience, I'd estimate a rate around $120 per hour, which is on the lower side for a marketing and research expert in San Francisco. This is because the market rate for such professionals in the Bay Area can range from $150 to $250 per hour, depending on the specific job requirements and the candidate's level of experience. However, since Rustom's skills are not overly specialized and he has experience in nonprofit management, I've rounded down to $120 per hour.
